Die normalerweise im Eingriff befindliche Drehmomentübertragungsvorrichtung gemäß der Erfindung ist in Fig. 1 allgemein mit 10 bezeichnet. Bei einer üblichen Anwendung wird die Vorrichtung 10 als normalerweise eingreifende Bremse verwendet und wird daher im folgenden als solche bezeichnet. Es ist natürlich zu erkennen, daß die Vorrichtung 10 auch bei Anwendungen brauchbar ist, bei welchen sie als Kupplung arbeitet.The normally engaged torque transmitting device according to the invention is generally designated 10 in FIG. 1. In a common application For example, the device 10 is used as a normally engaged brake and is therefore hereinafter referred to as such designated. It will of course be recognized that the device 10 is useful in applications in which it is used works as a clutch.
Die Bremse 10 weist ein Abtriebsorgan 11 auf, das über nicht gezeigte Bolzen, die in Blindbohrungen 12 im Abtriebsorgan aufgenommen werden, an einen Abtrieb angeschlossen werden kann. Das Abtriebsorgan 11 bildet ein Gehäuse und weist einstückig damit oder vorzugsweise, wie dargestellt, als getrenntes Organ, das durch Schweißungen 15 od.dgl. daran befestigt ist, eine Hülse 14 auf. Eine' oder mehrere axiale Keilnutenfedern 16 sind innerhalb der Bohrung 17 der Hülse 14 angeordnet. Mindestens eine und vorzugsweise mehrere Reibungsscheiben 18 sind innerhalb der Bohrung 17 gleitend geführt und werden in axialer Richtung auf den Keilnutenfedern 16 gelenkt.The brake 10 has an output member 11, which is via bolts (not shown) that are inserted into blind bores 12 in the output member be recorded, can be connected to an output. The output member 11 forms a housing and has integral therewith or preferably, as shown, as a separate organ, which by welds 15 or the like. to it is attached, a sleeve 14. One or more axial keyways 16 are within bore 17 of the sleeve 14 arranged. At least one and preferably a plurality of friction disks 18 are slidable within bore 17 and are guided in the axial direction on the keyway springs 16.
Ein Antriebsorgan kann an einen Antrieb angeschlossen werden und weist normalerweise einen Ring 19 auf, der an einer Welle angreifen kann, welche in einer Bohrung 13 des Abtriebsorgans 11 gelagert ist. Trennplatten 21 werden vom Ring 19 getragen und auf diesem in axialer Richtung durch die Keilnutenfedern 20 gelenkt. Die Reibungsscheiben 18 am Abtriebsorgan und die Trennplatten 21 am Antriebsorgan greifen in der üblichen Weise ineinander.A drive member can be connected to a drive and normally has a ring 19 which is attached to a Can attack shaft which is mounted in a bore 13 of the output member 11. Partition plates 21 are from Ring 19 carried and steered on this in the axial direction by the keyway springs 20. The friction discs 18 am The output member and the partition plates 21 on the drive member engage in one another in the usual way.
Eine ringförmige Druckplatte 22 ist innerhalb der Bohrung geführt und grenzt an die Reibungsscheiben 18 und Trennplatten 21 an. Eine Federanordnung ist innerhalb der Bohrung 17 geführt und drückt die Druckplatte 22 gegen die Reibungsscheiben 18 und die Trennplatten 21. Vorzugsweise weist die An annular pressure plate 22 is guided within the bore and is adjacent to the friction discs 18 and partition plates 21 at. A spring arrangement is guided within the bore 17 and presses the pressure plate 22 against the friction disks 18 and the separating plates 21. Preferably, the

24 und Ringe 25 einwirken, die in der Nut 26 in der Hülse sitzen. Ein Freigabeorgan ist innerhalb der Bohrung 17 zum wahlweisen Verschieben der Druckplatte 22 weg von den Reibungsscheiben 18 und den Trennplatten 21 geführt. Vorzugsweise ist das Freigabeorgan durch Druckmittel betätigbar und weist, wie in den Fig. 1 und 2 gezeigt, ein rohrförmiges Organ 27 auf, das an der Druckplatte 22 über Schnappringe 28 angreift, die in der Nut 29 geführt sind. Eine ringförmige Reaktionsplatte 30 ist gleitend und abdichtend innerhalb der Bohrung 17 geführt und umgibt das rohrförmige Organ 27. Vorzugsweise weist die Reaktionsplatte 30 Umfangsnuten auf, innerhalb welcher O-Ringe 31 geführt sind. Eine ringförmige Gegenplatte 32 ist ebenfalls gleitend und abdichtend innerhalb der Bohrung 17 geführt und umgibt das rohrförmige Organ 27. Die Gegenplatte 32 weist vorzugsweise Umfangsnuten auf, in denen O-Ringe 33 geführt sind und greift am rohrförmigen Organ 27 über Schnappringe 34 an. Eine Leitung 35 stellt Verbindungen zwischen der durch die Bohrung 14 gebildeten Kammer 36, dem rohrförmigen Organ 27 und den ringförmigen Platten 30 und 32 sowie einer Druckmittelquelle her.24 and rings 25 act, which sit in the groove 26 in the sleeve. A release member is within the bore 17 to optionally moving the pressure plate 22 away from the friction disks 18 and the separation plates 21 out. Preferably the release member can be actuated by pressure means and, as shown in FIGS. 1 and 2, has a tubular shape Organ 27 which engages the pressure plate 22 via snap rings 28 which are guided in the groove 29. An annular one Reaction plate 30 is slidably and sealingly guided within bore 17 and surrounds tubular member 27. Preferably the reaction plate 30 has circumferential grooves within which O-rings 31 are guided. An annular counterplate 32 is likewise guided in a sliding and sealing manner within the bore 17 and surrounds the tubular member 27. The counter plate 32 preferably has circumferential grooves in which O-rings 33 are guided and engages the tubular Organ 27 via snap rings 34. A line 35 provides connections between that formed by the bore 14 Chamber 36, the tubular member 27 and the annular plates 30 and 32 and a pressure medium source.
Normalerweise sind, wie in Fig. 1 gezeigt, die Reibungsscheiben 18 und die Trennplatten 21 durch die gegen die Druckplatte 22 zur Wirkung kommenden Federn 23 zusammengeklemmt, wodurch der Antrieb am Abtrieb festgelegt wird. Bei Eingabe von Fluiddruck in die Verbindung 35 und Unterdrucksetzen der Kammer 36 bewegt sich die Platte 32 nach rechts, betrachtet gemäß Fig. 2. Diese Bewegung zieht das rohrförmige Organ 27 nach rechts, wodurch die Druckplatte 22 von den Reibungsscheiben 18 und den Trennscheiben 21 weggeschoben und eine freie gegenseitige Drehung von Antrieb und Abtrieb ermöglicht wird.Typically, as shown in Fig. 1, the friction disks 18 and partition plates 21 are through against the pressure plate 22 coming into effect springs 23 clamped together, whereby the drive is fixed to the output. When entering of fluid pressure in connection 35 and pressurizing chamber 36, plate 32 moves to the right, viewed according to FIG. 2. This movement pulls the tubular member 27 to the right, whereby the pressure plate 22 is pushed away from the friction disks 18 and the separating disks 21 and a free mutual rotation of the drive and output is made possible.
